LUXEMBOURG (Reuters) - A top European Union court ruled against the inclusion of the Kurdistan Workers Party (PKK) on a list of groups whose funds must be frozen as part of the fight against terrorism on Thursday, citing procedural problems.

The Court of First Instance (CFI), the EU's second-highest court, said the EU had not properly justified its decision.

The Turkish government blames the PKK for nearly 40,000 deaths since the group launched an armed struggle for a Kurdish homeland in southeast Turkey in 1984.

The EU will seek to keep the PKK on its list of groups whose finances must be frozen as required by a United Nations resolution, EU officials have said previously.

Thursday's ruling followed similar judgments by the CFI that the EU had failed to give sufficient reasons for including groups on the list, including exiled Iranian opposition group, the People's Mujahideen.
